When the opening ceremony ended, Liard’s products all completed the opening ceremony. All the Lid people cheered and we won!
The 2008 Beijing Olympic Games put forward three concepts of green Olympics, science and technology Olympics, and humanistic Olympics. The characteristics and advantages of LED lighting and LED large screens are exactly what the three concepts need. The high-end video LED full-color display system adopted by Liard Company has high technical content and fully reflects the technology Olympics. The LED solid light source is the green light source of energy saving and environmental protection. The LED large screen is the best media to spread the Olympic spirit to the public. Liard regards participating in the Olympic project as a political task of glory and national prestige. It is also a strategic opportunity for the company to establish a global national brand. The company's strength is invested in this great and arduous work to add glory to the Olympics.
Liard Company is an integrator who has been focusing on LED application production for 12 years. It is a national semiconductor lighting engineering R&D and industry alliance unit. A total of nearly 140 million yuan of Olympic projects were completed.

The ground-level LED screen at the opening ceremony of the 2008 Olympic Games is by far the world's largest single-color full-color large screen with a total of 4564 square meters. The display requirements pose unprecedented challenges to the technical realization of terrestrial video LED display systems, which are reflected in the following three aspects. :
The scale is huge. The ground-based LED display screen of the opening ceremony is 147 meters wide and 22 meters high. The total number of pixels per line has reached more than 7K, and there are 2 deck covers and 2 axes of LED screen translation and fixed LED screen bite playback and signal. Processing, the playback system is large and complex.
There are many types of products. In the ground LED display, there are many types of LED products used, and in order to ensure the normal operation of the entire opening ceremony, the environmental adaptability requirements of the products are extremely strict, and the reliability requirements are extremely high, including the ground LED screen and the field control equipment must be reached. IP68 standard, various newly developed and customized LED display products such as independent power supply, synchronous playback and processing of ultra-light screen on the surface of the drawing axis.
LED installation is complicated. The LED screen has many different types of blocks, and there are many moving screens, including the vertical lifting stroke of the LED table from 7 meters to 29.5 meters, and the 18 meters horizontal stroke of the LED screen of the platform. The quick removal and removal time of the ground LED screen installed at a specific location, that is, the second floor mesa of the central 20-meter-diameter circular lifting platform is demanding.
Liard Company is responsible for drawing all the moving parts and display control parts such as the shaft and the deck cover. The requirements are high and difficult. The LED large screen produced by the company adopts the newly developed high-end video LED full-color display system, which is the first in China and adopts many international leading technologies:
LED single point brightness and chromaticity correction to improve the uniformity of the entire screen. The introduction of special equipment imported from the United States, combined with digestion and absorption and self-developed control system, corrects the brightness and chromaticity of each pixel, and fundamentally eliminates the mosaic phenomenon.
First-class image quality. The 10-level image grayscale output is realized by the broadcast-level video processing device. The 12-bit precision brightness and color correction ensures the accurate color reproduction capability of the display system and the brightness deviation of the whole screen less than 3%. 16-bit color processing The ability to make the color combination of the entire screen reach 281 trillion colors.
Beautiful and unique structure design. The box body adopts special mold to open the mold, the appearance is exquisite and fine, the special process guarantees the overall precision, the flatness tends to be perfect, the protection grade reaches IP65, the service life is long, safe and reliable, and the installation is convenient.
The 2008 Olympic Games is a big event for the Chinese people. This is a way to show the world what is happening in China today and in this land. Liard is proud to participate in the Olympic project and show the company the national industry of the company, and also to the company's products. The higher requirements have created conditions for Liard to enter the international arena. Participating in the Olympics is a rare opportunity.
Beijing has a solemn promise when it comes to the Olympics: to make the 2008 Olympic Games the greatest and most successful Olympic Games in human history. To achieve this goal, one of the most successful opening ceremony is as important as a jackpot. In the opening ceremony of the Beijing Olympic Games, in addition to the excellent ideas of previous Olympic Games and the rational use of high-tech means such as sound and light, how to reflect the characteristics of holding the Olympic Games in China has also become the focus of everyone's attention. Not only must we face the people of the country, but we must also face the world. The LED large ground display will definitely add a bright touch to the opening ceremony of the Beijing Olympic Games.
